Solution Overview
Problem
Current object recognition technologies are ineffective in capturing the visual attention of viewers under changing environmental conditions, particularly in distracting environments like those encountered by drivers.
Innovation Solution
The system modulates light outputs to elicit targeted vision responses by dynamically selecting wavelengths of light and patterns based on sensed environmental parameters, such as the quality of light and color of the scenery, to enhance object perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If standard passive approaches (bright colors, contrasting colors, light reflectors) are used for object recognition, then object visibility is improved under good lighting conditions, but object perception effectiveness deteriorates under changing environmental conditions and in distracting environments
Solution Approach 1:
The patent applies dynamics by transitioning from static, passive visual markers to dynamic, active light-emitting systems that continuously adapt their color output based on real-time environmental conditions. The system dynamically adjusts light wavelength selections to maintain effectiveness across varying lighting conditions, viewer distances, and environmental contexts, thereby resolving the contradiction between initial visibility improvement and subsequent reliability deterioration.
Solution Approach 2:
The system changes the parameter of light wavelength selection based on sensed environmental conditions. By adjusting the wavelength parameters of emitted light according to ambient lighting, viewer distance, and environmental context, the system maintains optimal object perception effectiveness across diverse conditions, preventing the deterioration that occurs with fixed-color passive approaches.
2Device complexity
If light emitting devices use one color of light at a time (continuous or blinking), then the device complexity is reduced, but the ability to elicit targeted vision responses under changing environmental conditions deteriorates
Solution Approach 1:
The patent implements multi-functionality by enabling the light-emitting device to perform multiple functions: it can emit various wavelengths of light, sense environmental conditions, process viewer distance and context information, and dynamically adjust its output to elicit different types of vision responses. This universal capability allows a single device to adapt to diverse environmental conditions and viewer scenarios, resolving the contradiction between simple single-color emission and the need for targeted vision response elicitation.
Solution Approach 2:
The system dynamically transitions between different light wavelengths and emission patterns based on real-time environmental sensing and viewer context. This dynamic behavior enables the device to elicit targeted vision responses appropriate for each situation, whether that requires attention-grabbing flashes, subtle color changes, or sustained illumination, thereby achieving high adaptability without requiring permanently complex hardware.
3Reliability
If sensors and processing are added to dynamically change light outputs based on environmental conditions, then object perception effectiveness is improved, but the device complexity increases
Solution Approach 1:
The system applies self-service by incorporating environmental sensors that automatically detect lighting conditions, viewer distance, and contextual factors, with the processing unit autonomously determining appropriate light wavelength selections and emission patterns without external intervention. This self-contained adaptive capability improves object perception effectiveness while managing complexity through integrated, autonomous operation rather than requiring external control systems.
Solution Approach 2:
The patent implements feedback mechanisms where sensors continuously monitor environmental conditions and viewer context, and the processing unit uses this feedback to dynamically adjust light wavelength selections and emission patterns. This closed-loop feedback system ensures optimal object perception effectiveness by constantly adapting to changing conditions, while the integrated feedback architecture manages complexity through unified sensor-processing-emission integration rather than separate complex subsystems.

Data Source
AI summary
A system and method for object perception is provided comprising one or more sensors for sensing and delivering to a processor environmental data inputs with reference to an object viewing point. The processor uses the data inputs to determine and select light outputs to be emitted from one or more displays. The light outputs are modulated to comprise one or more wavelengths of light that elicit one or more targeted vision responses in order to facilitate object perception from the object viewing point. The light outputs can be modulated according to how the environmental parameters sensed change over time (e.g light conditions). Light outputs may include the emission of equiluminance based wavelengths of light and peak sensitivity wavelengths of light to elicit peripheral and foveal vision responses, respectively.
